Others reported its isola- tion from different species of the genus including the Egyptian Echinops spinosus L. without any mention to the detection of echinorine .

The fact about echinopsine and first isolation of echinorine from Echinops spinosus L. Controversial studies were obtained about the natural existence of echinopsine. Some studies considered it as an artifact formed from a apinosus quaternary amine alkaloid called echinorine during alkali treatment of the plant extract.
Others reported its isola- tion from different species of the genus including the Egyptian Echinops spinosus L.
In this study, echinopsine was proved to be a natural al- kaloid after its isolation from Echinops spinosus L. Moreover, this study reports the first isolation and spectral identification of echinorine from the title spe- cies. Echinopsine; echinorine; Echinops spinosus L.
